What is a Pulsed Laser?
A pulsed laser is a type of laser that emits energy in short, intense bursts rather than a continuous beam. These pulses typically last from nanoseconds to femtoseconds and deliver high peak power that enables precise material processing. Pulsed lasers are widely used in applications where high accuracy and minimal heat-affected zones are essential, such as micromachining, medical treatments, and laser cleaning.
Unlike continuous-wave lasers, pulsed lasers can focus extreme energy into tiny time intervals, making them ideal for delicate and high-precision tasks.
Understanding Pulsed Fiber Lasers
A pulsed fiber laser is a specific type of pulsed laser that uses a doped optical fiber as the gain medium. It offers several advantages over traditional solid-state lasers, such as:
High beam quality
Excellent power efficiency
Compact and robust design
Long operating life with minimal maintenance
Due to their precision and reliability, pulsed fiber lasers are commonly used in metal marking, deep engraving, fine cutting, and surface texturing applications.
Whether you’re marking stainless steel or cleaning rust from metal surfaces, a pulsed fiber laser offers the perfect balance between speed and accuracy.
What Determines Pulsed Laser Power?
Pulsed laser power is typically measured in terms of peak power and average power. Peak power refers to the maximum energy delivered during a single pulse, while average power measures the energy output over time.
The pulsed laser power is determined by key factors such as:
Pulse duration (shorter pulses = higher peak power)
Pulse frequency (Hz or kHz)
Energy per pulse (measured in millijoules)
Repetition rate
Understanding these parameters is crucial for selecting the right pulsed laser for your specific application, ensuring both efficiency and precision.
Applications of Pulsed Lasers
Pulsed lasers, particularly pulsed fiber lasers, are used in a wide range of industrial and scientific applications, including:
Metal and Plastic Marking
Fast, permanent marking of barcodes, serial numbers, and logos without damaging the substrate.
Surface Cleaning
Efficient removal of rust, oxide layers, paint, and oil from metals using controlled pulsed laser power.
Micromachining
Precise drilling, cutting, and structuring of materials in electronics and semiconductor industries.
Medical Applications
Used in dermatology for tattoo removal and skin resurfacing thanks to their precise energy delivery.
3D Printing and Additive Manufacturing
Used in powder bed fusion technologies to selectively melt materials.
Why Choose Pulsed Fiber Laser Technology?
Choosing a pulsed fiber laser means investing in high-performance, low-maintenance laser technology. Here are the key advantages:
High energy efficiency
Maintenance-free operation
Unmatched precision and control
Ideal for heat-sensitive materials
Long service life (up to 100,000 hours)
Whether for industrial or scientific use, pulsed lasers provide reliable and consistent results in demanding environments.
Conclusion
As industries move toward smarter, cleaner, and more precise manufacturing processes, pulsed laser and pulsed fiber laser technologies are playing a vital role. Their high pulsed laser power, combined with precision control, makes them indispensable tools for modern applications.
